Why do you use "commute" for designation of travelling? The word "commute" derives from latin "com-" (means inter-) and "mutare" (means change). I pondered a little why do you use "commute" when you talk about travelling, but though your opinion is wanted. We Russians have similar notions, e.g.: He commuted the forth decade (means He is older then forty year). He commutes for trifles (means He is offened by minor troubles). But we rare (read: never) use this word while speaking about short travellings, e.g. on a suburb train. Thank you
